A hydrogen cylinder is designed to withstand an internal pressure of 100 atm. At 27° C, hydrogen is pumped into the cylinder which exerts a pressure of 20 atm. At what temperature does the danger of explosion first sets in?

Question

A hydrogen cylinder is designed to withstand an internal pressure of 100 atm. At 27° C, hydrogen is pumped into the cylinder which exerts a pressure of 20 atm. At what temperature does the danger of explosion first sets in? (A) 500 K (B) 1500 K (C) 1000 K (D) 2000 K

Constant volume process P V=n R T (P1/T1)=(P2/T2) (20/300)=(100/T2) T2=1500 K

Q. A hydrogen cylinder is designed to withstand an internal pressure of $100 a t m$ . At $2 7^{\circ} C$ , hydrogen is pumped into the cylinder which exerts a pressure of $20 a t m$ . At what temperature does the danger of explosion first sets in?

500 K

1500 K

1000 K

2000 K

Constant volume process
$P V = n RT$
$\frac{P _{1}}{T _{1}} = \frac{P _{2}}{T _{2}}$
$\frac{20}{300} = \frac{100}{T _{2}}$
$T_{2} = 1500 K$
